Procedure

To a suspension of 2-[2-(2-oxoimidazolidin-1-yl)ethoxy]benzaldehyde oxime (20.2 g, 0.081 mol) in CH2Cl2 (400 mL) at −1° C. is added, dropwise over 10 minutes, an aqueous NaOCl solution in water (157 mL, Aldrich, >4% of active chlorine). The reaction medium is then stirred for 20 minutes. The aqueous and organic phases are separated and the aqueous phase is extracted with CH2Cl2 (twice 75 mL). The combined organic phases are washed with water (3 times 10 mL) and dried over Na2SO4. The phases are concentrated to 100 mL under reduced pressure at room temperature. 50 mL of petroleum ether are added. The solution is cooled to −18° C. (3 hours). The precipitate is filtered, washed with CH2Cl2/petroleum ether (5 mL/10 mL; then 5 mL/20 mL; then 0 mL/20 mL) and then dried under atmospheric pressure at room temperature.
